Era is used to mark the boundaries of geological time scale by using radio carbon dating technique.
Explanation:
Geological time starts with Precambrian time.
Geologically, time is divided between the Precambrian era and present time into era.
The three eras are Paleozoic era, Triassic period and Cenozoic era.
Era is further divided into periods.
Scientists use radio carbon dating to study fossils and rock formation. With this study they were able to divide them in exact geological scale.
Geologic scale is the record of events in earth's history and evolution.
When you shower with hot water, everytime you get out the shower, outside it is cold, but inside it is hot due to the hot gas particles. When you shower with cold water, it is the opposite.
Answer:
increase anxiety; decreased vulnerability to overreact to stress
Explanation:
Serotonin (5-HT) is a natural neurotransmitter that carries signals between nerve cells (neurons) throughout the body. This neurotransmitter (serotonin) is responsible for regulating many biological functions (e.g., mood, digestion, sleep, etc). Moreover, it has been shown that there is an association between low cerebrospinal fluid 5-hydroxyindole-acetic acid (5-HIAA, the principal serotonin metabolite in the brain) levels and the risk of developing depression or destructive behaviors. In addition, serotonin concentration can also be elevated in situations of anxiety and/or stress. Antidepressants such as Prozac, Zoloft and Paxil act as serotonin uptake inhibitors that increase serotonin concentration at the synaptic site. Like other drugs, these antidepressants may lead to increase anxiety and decrease the vulnerability to react to stress by downregulating sensitivity to serotonin released during natural stress situations.
The given question is incomplete question as it lack essential part of question which is :
Ex: Write a hypothesis about the worms and lima bean plants. Be sure to answer the lab question.
Answer:
The correct answer would be : If plants grow in soil with worms, then growth of the lima bean plant will be greater due to worms helps in decomposing organic matter.
Explanation:
In this hypothesis the one species benefits other species in the same ecosystem they both exist. According to the hypothesis presence of the worms helps in the growth of the lima bean plants.
Dependent variable is a variable that depends on change in independent variable. Here the change in the presence of worms affects the growth of the bean plants so, the dependent variable is bean plant and the independent variable is presence of the worms.
Thus, the correct answer is : If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter
